Expert review
About this product
The Springfield Armory Hellion is a bullpup-configured semi-automatic rifle that delivers full-length 5.56 NATO ballistic performance in a compact 28.25-inch overall length package through its efficient bullpup layout. Based on the Croatian VHS-2 platform with documented military service, the Hellion arrives stateside as a factory-built semi-auto variant from a major U.S. manufacturer. Its core design brief was solving the patrol rifle versus carbine length dilemma without entering NFA-regulated Short-Barreled Rifle territory.
What is the Springfield Hellion used for?
The Springfield Hellion bullpup is designed as a practical patrol, defensive, and general-purpose rifle where a short overall length is more critical than a traditional layout. It provides the full muzzle velocity and terminal performance of a 16-inch barrel AR-15 while eliminating over 8 inches from the overall package, making it substantially more maneuverable in vehicles or structures. The adjustable gas system accommodates suppressor use without modifying the rifle, and the fully ambidextrous controls make it suitable for left-handed shooters out of the box.
How does the Springfield Hellion compare to the IWI Tavor X95?
The Springfield Hellion directly competes with the IWI Tavor X95, offering a different balance of modularity versus proven simplicity. The Hellion's superior feature is its two-position adjustable gas system, allowing immediate optimization for standard ammo or suppressor use without tools, while the X95 requires a dedicated suppressor gas plug. However, the X95 maintains an edge in trigger feel; its factory single-stage pull is typically measured around 7-8 lbs, while the Hellion's longer, heavier polymer linkage results in a consistent 10-lb pull weight that demands deliberate shooter input.
What does it weigh and what are the dimensions?
This rifle weighs 8.0 lbs unloaded and measures 28.25 inches in overall length with a 16-inch barrel, making it over 7.5 inches shorter than a standard 16-inch AR-15 carbine. The bullpup configuration places the action behind the pistol grip, keeping the 16-inch barrel and sight radius intact while shrinking the footprint to near-PDW dimensions. For perspective, its 28.25-inch length is nearly identical to an AR-15 pistol with a 10.5-inch barrel and fully extended brace, but the Hellion accomplishes this legally as a Title I rifle, avoiding the paperwork and compliance issues of the NFA-regulated SBR or pistol brace route.
Who is this NOT for?
The Hellion is not for traditionalists who exclusively train on AR-15/M4-pattern controls or competitors who prioritize ultra-lightweight builds and match triggers. The bullpup manual of arms requires distinct muscle memory for magazine changes and bolt release location, and the trigger, while reliable, lacks the crisp break of a quality mil-spec AR unit. Shooters accustomed to the vast accessory ecosystem of the AR-15 will find handguard and optic rail compatibility more restrictive, requiring specific-height mounts to achieve proper cheek weld with the included adjustable stock.
What's in the box?
You receive one complete Hellion rifle, one 30-round Magpul PMAG, a comprehensive operator's manual, and a Springfield Armory lock. The rifle ships with its 4-prong flash hider installed and its gas adjustment lever set to the unsuppressed position. The integrated folding front and rear sights are deployed, and the reversible ejection port cover is installed for right-hand ejection. Unlike some competitors who ship their rifles in minimal cardboard, Springfield uses a fitted polymer hard case that provides legitimate storage and transport protection.
Is the Springfield Hellion worth it at $1,842.99?
At its $1,842.99 MSRP, the Hellion commands a premium over a basic AR-15 but delivers specific value for the shooter who needs its compactness and ambidextrous features in a factory-compliant package. You are paying for a military-proven short-stroke piston system, fully ambi controls, an adjustable stock, and integrated sights that would cost hundreds extra on an AR build. For a dedicated home-defense tool or a patrol rifle where length matters more than absolute modularity, it's a justifiable investment compared to the cost and legal complexity of building a comparable AR-15 SBR. If your needs are better served by a traditional rifle for hunting or target shooting, consider a more conventional platform like the Stevens 334 in .308 Win.

Pros & cons
What works
- 16-inch barrel in a 28.25-inch overall length — 7.5+ inches shorter than a standard AR-15 carbine
- Two-position adjustable gas system — tool-less switching between standard and suppressor settings in under 3 seconds
- Fully ambidextrous controls — reversible ejection, magazine release, and safety for left-handed use out of the box
- Integrated flip-up sights — rear aperture has 5 distinct settings for precision adjustment
Trade-offs
- Heavy 10-lb trigger pull — a direct result of the long polymer trigger linkage inherent to the bullpup design
- Restrictive handguard — limited M-LOK real estate compared to modern AR-15 rails, complicating light/laser placement
- High bore axis — requires specific low-profile optic mounts to maintain proper cheek weld with the stock riser

Frequently asked questions
- Does it work with standard AR-15 magazines?
- Yes, the Springfield Hellion uses STANAG-pattern magazines identical to the AR-15, including Magpul PMAGs, Lancer L5AWM, and USGI aluminum mags. The included magazine is a Magpul PMAG Gen M3. The magazine release is ambidextrous and requires a firm inward press to drop the mag free.
- Is the barrel threaded for a suppressor?
- Yes, the 16-inch barrel features a standard 1/2x28 TPI thread pattern under the 4-prong flash hider, compatible with most .223/5.56 muzzle devices and direct-thread suppressors. The two-position gas system has a dedicated suppressor setting to reduce gas blowback when running a can.
- Can the ejection side be switched for left-handed shooters?
- Yes. The ejection is reversible from right to left in under 2 minutes. The process involves removing two captured pins to swap the bolt and ejector assembly, then reinstalling the ejection port cover on the opposite side. Full instructions are in the manual.
- What optics mounts are recommended?
- Due to the high integrated Picatinny rail, you need a low-profile mount. A 1.5-inch height mount from American Defense Manufacturing or a Unity Tactical FAST mount provides proper alignment with the stock's cheek riser. Standard AR-height rings will position the optic too high for a consistent weld.
- How long does shipping take to an FFL?
- Ironclad Armory processes in-stock firearms for shipment within 1 business day. Transit time via FedEx to your selected FFL dealer averages 3-5 business days. You will receive tracking information once the firearm is scanned by the carrier.
- What is the warranty?
- Springfield Armory provides a limited lifetime warranty for the original purchaser, covering defects in materials and workmanship. Warranty service must be initiated through Springfield; Ironclad Armory facilitates the initial contact and RMA process if needed within the first 30 days of purchase.
